Attorneys for a West Texas prosecutor will begin presenting their defense Friday in his trial on charges that he helped a doctor retaliate against two whistle-blowing hospital nurses. State prosecutors rested their case Thursday against Winkler County Attorney Scott Tidwell, who is charged with two counts each of misuse of official information, retaliation and official oppression by using his position to retaliate against the nurses. Misuse of official information and retaliation are third-degree felonies, and each count is punishable by up to 10 years in prison.
